In recent years, small 1-5W amplifiers have surged in popularity. While they are enjoyable, some may appear more toy-like than genuine amplifiers. Palmer's EINS was crafted as a serious, true tube amplifier for professional use. Its speaker-simulated output enables direct connection to an audio interface without needing a speaker, thanks to the integrated loadbox. The unique "HiZ output" allows for direct connection to any amplifier's input, enabling the EINS to be used for power boosting, as a preamp, or even integrated into a pedalboard setup.

The standard configuration for the Palmer EINS includes an ECC83 preamp tube (V1) and an ECC82 (V2) power stage tube. Alternate tube configurations are also possible.
